Bookshelf Framing Question

[abnjumpmaster]

My pole barn has 6x6's that are 10 feet apart. Is that too far apart to do bookshelf framing? Will the 2x6's sag in the middle? I am planning on spacing each horizontal 2x6 22 1/2 inches apart. I was not going to toenail, but instead use 2x6's in between each shelf nailed vertically to the 6x6's (22 1/2 inches long).

Is this correct and will it work?

Sounds like a good plan. Just remember the best strength in the 2 x 6 is when it is in the turned up "edge to the sky", not laying flat over a span . JMO

Are you planning on placing the 2 x 6 s flat and using them for shelves? How much weight might you put on them? I think you may well experience sagging if any weight is placed in the middle. Why not just frame up 10 foot sections of 2 x 4 wall and erect flush with the posts?

10' span will sag if you put any real books on it. With that length cut a few more at 22.5" and run them at the 5' mid point.

yep.

My posts are 12 foot spacing and walls are framed as you describe. They will sag some under their own weight, so make sure they are straight before you screw the tin on.

32" is the limit for a fully loaded bookshelf out of 1x material. I would look at 48"-60" in 2x material.

This is called a commercial girt and yes you can do it on a 10' span.. If you look at my build you will see it done on part of my building. One thing to pay attention to is the bottom & top boards. If it is on the outside of the pole then you have a couple of things to think about. If the girt is flush with the outside of the pole then the metal will flare out at the bottom. You can offset the girt to be outside the pole by 1.5" or use a 2x8 girt.

In a pole building the wind load can be quite high and the commercial girt will keep the wall from flexing as much. There is argument for either orientation in this case.
